This is true... and the "shareware" (first episode) doesn't cost money on Android.
If you like it, the second and third episodes, can be bought for a small amount each.

I have played Duke games on pretty much every system any were ever made, but it is my opinion that the controls make Duke 3D for Android the least desirable Duke Nukem control scheme I have ever played.

Interesting... if includes keyboard support, my Xperia Play will make Android Duke Nukem an enjoyable experience. Of course joystick controls could be had on the Xperia Play also... with a bit of work.
